- Abstract
This study investigated the inclusion of grape poma ce silage (GPS; 0, 10, 20 and 30%) were evaluated in diets of lambs on nutrient intake and digestibility, nitrogen balance and ingestive behavior. Four lambs of the Santa Inês breed with weight of 21.93 ± 0.87 kg and approximately seven months old, were ho used in metabolic cages and distributed in a 4x4 latin square design. The treatments consisted of four diets with the inclusion of 0, 10, 20 and 30% GPS in diets. The nutrient intake was observed an increasing linear behavior for ether extract (EE) intake ( P <0.05) according to the increase of EE in the diets, caused by content of EE of seeds in GPS. The diets did not differ in the digestibility coefficients of nutrients and nitrogen balance ( P >0.05), with average digestibility of dry matter digestibility (DDM) of 678.6 ± 0.62 g kg -1 DM and average retention of 239.78 g kg -1 N ingested of N. The ingestive behavior the diets were influenced ( P <0.05) by only the length of time that the animals remained idle in standing. This parameter showed a quadratic behavior with a maximum point estimated at 17.73 % of GPS ( P =0.041). In conclusion, the use of GPS can be used until inclusion level of 30 % without negatively affecting the parameters evaluated.
